Detailed description of the invention
Fig. 1 to Fig. 3 shows for choosing flat pack that with a kind of delivery system flat pack that and non-flat package separated in the package from a large amount of supply.As used in the present note, term " flat pack that " refers to envelope and other packages with little thickness; Term " non-flat package " refers to, such as, is not the box of " flat pack that " and multiple packages of pipe.The package P therefrom choosing a large amount of supplies of flat pack that is poured onto on the conveyer 10 of a cross-feed.The conveyer of this cross-feed may be implemented as the belt conveyer with a belt 12, and this belt can be flat belt or flat-top modular plastic moving belt.These packages are sent in batches on a slope conveyer 16 by belt on direction of transfer 14.
Shown slope conveyer is the moving belt 18 of a deflection, and the moving belt of this deflection has multiple stop element 20 (scraper plate as short), and these stop elements extend across the width of belt at regular intervals along the length of belt.These stop elements can extend past whole width as shown in the figure or can extend past the half of the width interlocked to its right hand half from the left hand half of belt.The transmission surface of the belt 18 of deflection is divided into multiple holder 22 by these stop elements, each holder comprise this that supply from the conveyer of this cross-feed in enormous quantities a collection of package of receiving.This slope conveyer is left horizon with a tilt angle alpha by inclination, and this angle is enough to larger non-flat package on the top of a permission storehouse or even flat pack that is rolled backward or slides, until they arrive these stop elements.The moving belt 18 of deflection upwards advances on this slope with continuous print start and stop campaign.The impulse movement jolted of belt also helps stacking package that heap superimposition superposition does not occur.Rubber on the transmission surface of the belt of deflection or other high friction pads or region can be used for replacing multiple scraper plate to be used as multiple stop element.These pads provide enough frictions and slip over to prevent package.
Package is dropped on a moving belt 24 tilted by the moving belt 18 of deflection from its upper end.The moving belt tilted can be implemented as a flat rubber tape or a modular plastic friction-top belt, as what made by the Intralox limited liability company system of the Louisiana, United States Harrar Chinese and sold
series 1400 friction-top belt (
series 1400 Friction Top belt) or
series 900 diamond crown friction belts (
series 900 Diamond Friction Top belt).It is that major part is covered by a kind of high friction elastomeric that surface 26 is transported in the outside of these modular height friction belts.Alternately, the belt of inclination can become high friction by carrying out veining process to transport surface, one normal low friction outside.Under any circumstance, the frictional behavior of outside face, if belt is to the friction coefficient presented bottom package and the inclination angle beta being selected to the belt keeping flat pack that F, the outside that the bottom of these flat pack that is still in belt is transported on the surface, allows non-flat package N to cross belt and through a lower side 29 from side 28 rolling downwards of the rising of the belt tilted simultaneously.Certainly, be stacked on other package tops or throw into inclination conveyer edge on the flat pack that non-flat package that can roll with these equally together with fall through lower side.The moving belt 24 tilted transmits these flat pack that F be kept on the direction 30 that belt is advanced.Parallel and the level being adjacent to the lower side 29 of the moving belt 24 of inclination is collected conveyer 32 and has been received and to roll all non-flat package N of getting off and a small amount of flat pack that from the belt tilted, and transmits these packages on the direction 30 that belt is advanced.The package that these are divided initially all is delivered on selection conveyer 34 to provide further selection where necessary by moving belt 24 and the main conveyer 32 transmitting the level of non-flat package of the inclination of main transmission flat pack that.
Although the outside surface of transporting of the height friction of the moving belt of described inclination forms a kind of holding device, this holding device is used for preventing flat pack that from sliding off the lower side of the moving belt of inclination, also can use other holding devices.Such as, from outside transport surface 26 erect and along its length close to this inclination moving belt 24 compared with low side edge 29 extend a protruding obstacle 33 are another kind of holding devices, this another kind of holding device can be used for catching these flat pack that and prevent them from sliding off lower side.If use a protruding obstacle, so this transmission surface is not to show high frictional behavior.The height of this obstacle can be small, as long as it enough highly to slip over to prevent bottom to be sitting in outside flat pack that of transporting on surface.This obstacle along the length of moving belt tilted can be continuous print or it can be segmentation.
Selection conveyer 34 comprises a roll-type moving belt 36 (equally shown in Fig. 4 to Fig. 6), and this roll-type moving belt has from the outstanding multiple package backing rolls 38 of its outside face.These rollers are arranged to and rotate in first direction 40 and rotation in contrary direction 42 in a downstream part 43 in a upstream portion 41 of selection conveyer 34.In this way, package is pushed to the first side of roll-type moving belt substantially in upstream portion along the path of on the direction of arrow 46, and in downstream part, is pushed to relative second side 45 along the path on the direction of arrow 47 substantially.Roll-type moving belt 36 is implemented as
series 7000 roller type leather belts, wherein these rollers 38 extend past the thickness of belt and rotate on the axle 48 of direct of travel 50 being parallel to belt.When roller type leather belt advances on direct of travel (outside the page in Fig. 4), these rollers activate by being installed to the multiple Passively activated roller 52 shelved in the conveyor frame of leather belt roller in the upstream portion of conveyer.A kind of form of such roller type leather belt conveyer activated pays Buddhist nun (Matthew L.Fourney) U.S. Patent number 7 being published on " delivery system (Conveyor Systems for Diverting Objects) for transferring objects " on March 24th, 2009 being repaiied L by horse, 506, described in 751.The disclosure content of this patent is in the present note combined by reference.
One of long and narrow live roll 54 form selection element extends along the length of selection conveyer in upstream portion, and it compared with horizontal conveyor 32 by lateral alignment closer to the side 28 of the rising of the moving belt 24 tilted.Live roll is continuously moving in the direction in the diagram indicated by arrow 56.Vertical gap 58 between the bottom of live roll 54 and the top of these leather belt rollers 38 is enough large, passes to allow multiple flat pack that F but does not allow multiple non-flat package N to pass.Live roll 54 rotates in following direction, and the face 60 of these non-flat packages come in contact the side of the roller relative with the first side 44 in this direction upwardly.This flat pack that making non-flat package pivotably be lifted away from them to be stacked, to allow non-flat package to be pushed through gap through belt in the direction of the arrow 62, thus crossing the first side 44, to arrive the dish 64 (Fig. 3) of a skewed slot or inclination upper to transport.
Live roll 54 by trending towards flat pack that being discharged in a wrong manner this gap is run into for preventing flat pack that, this live roll is equipped with a guiding piece 66, this guiding piece has a lower surface 68, this guiding piece prevents from contacting with roller through the flat pack that F in gap, as shown in Figure 5.The upright position 70 of this guiding piece 66 can be adjusted to arrange the maximum ga(u)ge allowed through the flat pack that in gap.This maximum ga(u)ge is the distance between the top of these leather belt rollers 38 in the lower surface 68 and roll-type moving belt of this guiding piece.
Pull flat pack that F by the down suction below live roll 54 for helping further, one or more power distributing rollers 72,73 with the S. A. 74 being parallel to live roll 54 can be positioned at the first side place of roller belt 36.Flat pack that F is dragged in this gap by the clamping point of each other 76 by these distributing rollers, and pulls flat pack that through this gap and be discharged on flat pack that collection chute 64.In this way, these distributing rollers supplement these leather belt rollers 38 by flat article is moved through the gap below live roll 54.Indicated by the arrow 78,79 of Fig. 6, two distributing rollers can be supplied with power and carry out contrarotation, or in these distributing rollers one can be the nip rolls that of being biased towards power distributing roller is passive.
In some instances, the upstream portion 41 of last selection conveyer 34 may only be needed.If but many packages arranged side by side go wrong, then downstream part 43 can use together with the live roll 55 similar with, to form a secondary selection conveyer.The live roll 55 in downstream extends along the length of the downstream part of selection conveyer, departs from the live roll 54 of upstream in the horizontal and rotates in the opposite direction stopped by other packages and the non-flat package arranged side by side that cannot engage with the live roll of upstream to lift closer to the second side 45.These are pushed to the second side of roller type leather belt by these leather belt rollers 38 in downstream part by the package transmitted, wherein by that stop, arranged side by side, that first non-flat package bumps against downstream live roll.Except in the flat pack that in downstream part through except the collection chute 65 arriving the second side place of conveyer below these rollers, the live roll in two parts operates similarly.Its exit end 80 can not be left through the higher non-flat package of the down suction arbitrary live roll and these leather belt rollers is restricted to roller type leather belt 36 by these live rolls.Therefore, flat pack that and non-flat package are separated by this delivery system automatically.
Shown in Fig. 7 is the another kind of form of choosing conveyer.Selection conveyer 82 is identical with the upstream portion of the selection conveyer of Fig. 3, except this selection element is implemented as a side protection device 84 instead of a live roll.The side protection device being illustrated as a upstanding wall can be positioned in the top on the surface of roll-type moving belt 36 or just outside at the side of belt.Gap 86 between these leather belt rollers 38 in the bottom of side protection device and roll-type moving belt allows flat pack that F to be pulled to by these leather belt rollers of rotating in arrow 86 direction below side protection device and by this gap.These flat pack that through this gap are left the side of belt and drop to as on the dish tilted of in Fig. 3 or skewed slot.These higher non-flat package N are stopped by side protection device and are transmitted by downstream on roll-type moving belt, on this roll-type moving belt, they can be collected or be delivered to a similar downstream selection conveyer part, and these leather belt rollers rotate with the direction that the downstream part of the selection conveyer with Fig. 3 is contrary and siding track is opposite side along conveyer in the portion.This gap can be constant (such as 0.25 inch) along the length of selection conveyer, or can increase along with the distance to downstream, does not occur stacking to help the flat pack that rested on other flat pack that tops.Multiple rollers 90 that the bottom of protective device is given prominence to from the side can be used to provide the Structure deformation with the low friction of flat pack that.As an alternative, this side protection device can by a kind of low friction, high-abrasive material (as UHMW plastics) makes.The many lines 92 dangled from the position the pedestal 94 be arranged on above roll-type moving belt or multiple pendle are dragging at the top of these packages transmitted along selection conveyer.These pendles are drawn flat pack that and are left the top of non-flat package and arrive on these leather belt rollers.
Although describe the present invention in detail about a kind of form, other forms are also possible.Such as, package can be placed on the moving belt of inclination by slope conveyer on the upstream termination of the moving belt tilted instead of on the side that it raises.As another example, more live roll part can be added on selection conveyer, can remove thing arranged side by side to provide more multimachine.And choose conveyer and can comprise a roll-type moving belt, the actuation roller of its middle and upper reaches is arranged to and rotates these leather belt rollers in one direction and the actuation roller in downstream is arranged to and rotates these leather belt rollers in the opposite direction, or this selection conveyer can comprise its multiple roller and is activated to the upstream moving belt and downstream moving belt that rotate in the opposite direction.In addition, this selection conveyer can independent of slope, inclination and the collection conveyer of level use, and vice versa.Like this, as these examples are advised, the scope of claims does not mean that the details to being used to describe particular version of the present invention limits.
